For loads of up to 18 tons / 22,500 lbs.
Tier 22 Loading is specified for areas such as driveways, factory floors, parking lots and off roadway applications subject to heavy forklift traffic and occasional vehicular traffic. The Tier 22 design load is 22,500 lbs. with a minimum failure load of 33,750 lbs.
Fibrelite trench covers can be custom molded moulded to be stepped, allowing them to be retrofitted into existing frames with shallow rebates while maintaining their structural integrity (independently tested).
This allows direct replacement of previously existing metal covers, or installation in existing precast or preformed concrete trenches. Stepping can also reduce manufacturing cost and weight.
